BD50HC0MEFJ-ME2

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The BD50HC0MEFJ-ME2 is a low-dropout linear regulator manufactured by ROHM Semiconductor, designed for automotive applications. It provides a fixed 5 V output with a maximum continuous current of 1 A. The device operates within an input voltage range of 4.5 V to 8 V and features a typical dropout voltage of 600 mV at full load. It is housed in an HTSOP-J8 surface-mount package and supports an operating temperature range from -40°C to +105°C. The component holds AEC-Q100 qualification.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated protection circuits including thermal shutdown and overcurrent protection to prevent damage during fault conditions.
• Capable of supporting functional safety analysis for automotive use cases.
• Includes a shutdown function that reduces circuit current to zero when disabled.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• Automotive electronic systems requiring stable 5 V power rails
• On-board devices needing high-accuracy voltage regulation
• Power management modules in automotive-grade environments

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the current lifecycle status before procurement, as this part is marked as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors or direct manufacturer channels. Ensure the HTSOP-J8 package compatibility matches your PCB footprint. Check for any specific handling requirements associated with automotive-grade components.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for designs requiring a fixed 5 V output with 1 A capability in automotive environments. Consider the 4.5 V to 8 V input range suitability for your supply voltage. Evaluate the HTSOP-J8 package for space constraints. Verify that the AEC-Q100 qualification meets your project's reliability standards. Note that it is not recommended for new designs due to lifecycle status.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This LDO belongs to ROHM's automotive-grade power management portfolio, specifically engineered for vehicle electronics. It shares the HTSOP-J8 package form factor with other variants in the series but differs in output voltage and current ratings. The BD50HC0MEFJ-ME2 is distinct from non-automotive versions like the BD50HC5WEFJ, which lack AEC-Q100 certification and functional safety support.
